Wi-Fi usb connector

when i try to get it to work,it opens the found new hardware thing, and it says: the system file cannot be specified. but it is connected. and in the installation wizard from the cd, it says, insert the USB connector int your computers usb port, but its already connected, so i click ok, and it says application error. what am i doing wrong?

well my Nintendo USB Connector worked for me perfectly.. i dunno why your's don't work.. hmm.. you have Window XP? and.. what is the error? are they numbers? 'cause if they are numbers.. you can go to nintendo.com and type the 5-6 digit number in and it'll tell you what the specific error is! :]

it doesnt give me a number, on the website, it says that a router could do something to make it not work. so i put my router ip adress in the bar, and i need a password to change it, but i dont know the password, is there another way? or do you know how to find the password
